The power component is used to drive the protective cover 11 to move. During operation, a base plate 1 is set up, and a pair of first support plates 2 are fixed to its bottom end to provide stable support for the entire device. The second support plates 3 fixed to both sides of the base plate 1 are used to enhance the stability of the U-shaped frame 7. The operator can place the glass sample on the placement plate 6 that slides along the first slide groove 4 to facilitate material feeding, unloading and position adjustment. The pair of U-shaped frames 7 are connected to the first U-shaped plate 9 through the connecting plate 8. The pressure block 10 is set at the bottom end of the first U-shaped plate 9 to form a pressurizing unit to apply detection pressure to the glass. Under the drive of the power component, the pair of protective covers 11 can automatically move and close during detection to completely seal the pressurizing area, effectively preventing glass fragments from flying when it breaks and avoiding personal injury.

[0024] The power component includes a first motor 12; the first motor 12 is fixedly connected to one side of the base plate 1; the output end of the first motor 12 is provided with a bidirectional lead screw 13; a pair of first through slots 14 are opened at the top of the base plate 1; one end of the bidirectional lead screw 13 extends into the first through slot 14 and is rotatably connected to the inner side wall of the first through slot 14; a pair of second sliders 15 are slidably connected in the first through slot 14; a pair of protective covers 11 are respectively fixedly connected to the top of the second sliders 15; the pair of second sliders 15 are respectively connected to the bidirectional lead screw 13 through a lead screw nut pair. During operation, by fixing the first motor 12 to one side of the base plate 1, when the operator starts the first motor 12, the bidirectional lead screw 13 rotates accordingly, driving the pair of second sliders 15 to slide in the through slot, thereby driving the two protective covers 11 to move in opposite directions until they contact and close, achieving complete sealing of the pressurized area.

[0025] A pair of first connecting posts 16 are fixedly connected to the top of the base plate 1; each of the first connecting posts 16 is slidably connected to a second connecting post 17 via springs; an arc-shaped clamping plate 18 is fixedly connected to one side of each of the second connecting posts 17; a second through groove 19 is opened on one side of each of the first connecting posts 16; a limiting block 20 is slidably connected to each of the second through grooves 19; a pair of protective covers 11 are slidably connected to the first connecting posts 16 respectively. During operation, a pair of first connecting posts 16 are fixedly connected to the top of the base plate 1, and the second connecting posts 17 are elastically connected to them via springs. When the power component drives the pair of protective covers 11 to move, the protective covers 11 will contact and push the limiting blocks 20, causing the second connecting posts 17 to drive the arc-shaped clamping plates 18 to gradually move closer, ultimately firmly clamping the placement plate 6 and the glass sample on it, ensuring that the entire placement system remains in a fixed position and does not move during the pressurization process.

[0026] A second motor 21 is fixedly connected to the top of the connecting plate 8; a first lead screw 22 is provided at the output end of the second motor 21; one end of the first lead screw 22 passes through the connecting plate 8 and is rotatably connected to the bottom end of the first U-shaped plate 9; a second U-shaped plate 23 is slidably connected inside the first U-shaped plate 9, and one end of the second U-shaped plate 23 passes through the first U-shaped plate 9 and is fixedly connected to the top of the pressure block 10; the second U-shaped plate 23 is connected to the first lead screw 22 through a lead screw and nut pair. During operation, by fixing the second motor 21 to the top of the connecting plate 8 and setting the first lead screw 22 at the output end of the second motor 21, when the operator starts the second motor 21, the first lead screw 22 rotates precisely under the drive of the motor, and the rotational motion is converted into linear motion through the lead screw and nut pair, driving the second U-shaped plate 23 to move smoothly downward along the inner side of the first U-shaped plate 9, thereby driving the pressure block 10 to move vertically downward, and finally making the pressure block 10 accurately contact the glass surface and apply a uniform and controllable detection pressure.

[0027] Each pair of first connecting posts 16 has a first groove 24 at its bottom end; each pair of second connecting posts 17 has a limiting plate 25 fixedly connected to its bottom end; the pair of limiting plates 25 are slidably connected in the first groove 24 respectively.

[0029] Working principle: A base plate 1 is set up, and a pair of first support plates 2 are fixed to its bottom end to provide stable support for the entire device. The second support plates 3 fixed to both sides of the base plate 1 are used to enhance the stability of the U-shaped frame 7. The operator can place the glass sample on the placement plate 6 that slides along the first slide groove 4, which is convenient for feeding, unloading and position adjustment. The pair of U-shaped frames 7 are connected to the first U-shaped plate 9 through the connecting plate 8. The pressure block 10 is set at the bottom end of the first U-shaped plate 9, which together form a pressurization unit to apply test pressure to the glass. A pair of protective covers 11 are driven by the power component. During testing, it can automatically move and close to completely seal the pressurized area, effectively preventing glass fragments from flying and avoiding personal injury. By fixing a first motor 12 to one side of the base plate 1, when the operator starts the first motor 12, the bidirectional lead screw 13 rotates accordingly, driving a pair of second sliders 15 to slide in the through groove, thereby driving the two protective covers 11 on both sides to move in opposite directions until they contact and close, achieving complete sealing of the pressurized area. By fixing a pair of first connecting posts 16 to the top of the base plate 1, the second connecting posts 17 are elastically connected inside by springs. When the power component drives the pair of protective covers 11 to move, the protective covers 11 will contact and push the limiting block 20, causing the second connecting column 17 to drive the arc-shaped clamping plate 18 to gradually move closer, ultimately firmly clamping the placement plate 6 and the glass sample on it, ensuring that the entire placement system remains in a fixed position and does not move during the pressurization process. By fixing the second motor 21 to the top of the connecting plate 8 and setting the first lead screw 22 at the output end of the second motor 21, when the operator starts the second motor 21, the first lead screw 22 rotates precisely under the drive of the motor, converting the rotational motion into linear motion through the lead screw and nut pair, driving the second connecting column 17 to move the arc-shaped clamping plate 18. The second U-shaped plate 23 moves smoothly downward along the inner side of the first U-shaped plate 9, thereby driving the pressure block 10 to move vertically downward. Finally, the pressure block 10 accurately contacts the glass surface and applies uniform and controllable detection pressure. Through the sliding fit structure between the limiting plate 25 and the first groove 24, a stable motion guide can be provided for the second connecting column 17, ensuring that it always maintains a vertical motion trajectory and preventing deviation. By setting a rubber pad at the bottom of the first support plate 2, the vibration generated during equipment operation can be effectively absorbed, preventing the vibration from being transmitted to the workbench or the ground, ensuring the stability of the hardness detection process and improving measurement accuracy.
